'Thyself' in the Bible

And Jonathan told David, saying, Saul my father seeketh to slay thee: now therefore, I pray thee, take heed to thyself in the morning, and abide in a secret place, and hide thyself:

Therefore deal kindly with thy servant; for thou hast brought thy servant into a covenant of Jehovah with thee: but if there be in me iniquity, slay me thyself; for why shouldest thou bring me to thy father?

And when thou hast stayed three days, thou shalt go down quickly, and come to the place where thou didst hide thyself when the business was in hand, and shalt remain by the stone Ezel.

Now therefore, my lord, as Jehovah liveth, and as thy soul liveth, seeing Jehovah hath withholden thee from bloodguiltiness, and from avenging thyself with thine own hand, now therefore let thine enemies, and them that seek evil to my lord, be as Nabal.
